Low Energy π-π Final State Interaction in the Veneziano Model

Final State Interaction Effects in B+→J/ψ π+ Decay

In this research the exclusive decay of                         is calculated by QCD factorization (QCDF) method and final state interaction (FSI). First, the  decay is calculated via QCDF method. The result that is found by using the QCDF method is less than the experimental result. So FSI is considered to solve the decay. For this decay, via the exchange of mesons are chosen for the intermedi...

Study of the rare Bs0 and B0 decays into the π+π−μ+μ− final state

Article history: Received 19 December 2014 Received in revised form 3 February 2015 Accepted 5 February 2015 Available online 11 February 2015 Editor: W.-D. Schlatter A search for the rare decays Bs → π+π−μ+μ− and B0 → π+π−μ+μ− is performed in a data set corresponding to an integrated luminosity of 3.0 fb−1 collected by the LHCb detector in proton– proton collisions at centre-of-mass energies o...

Final State Interactions and CP Violation in K L → π + π −

Using chiral perturbation theory we calculate the imaginary parts of the KL → π+π−e+e− form factors that arise from ππ → π+π− and ππ → π+π−γ∗ rescattering. We discuss their influence on CP violating variables in KL → π+π−e+e−. ⋆ Work supported in part by U.S. Department of Energy Grant No. DE-FG03-92-ER40701. † Work supported in part by U.S. Department of Energy Grant No. DE-FG02-91-ER40682.
